Re: Drilling (Need some information)
Post #3, picture #1. Better, sharper, larger pictures of those stamps would help. The shape of the crowns over the letters, which letters there are, numbers inside circles, they all mean something.
Try sprinkling some baby powder on there and then wipe it with your finger. That should clear the surface but all the stamps should stay filled with baby powder, giving nice white markings to examine.
